Are Uveres argiades and corctas distinct species ? 373' 



evidence to the contrary, I believe the differences in the- 

 appendages to be rather beyond mere geographical varia- 

 tion. As regards parrhasius and dipora, I am not prepared 

 to give any fully considered opinion. My material and 

 information are much too scanty. The original descriptions 

 of parrhasius and certainly of dipora are more applicable 

 to argiades than to the species I choose to call parrhasius, 

 and if this be not parrhasius then it is unnamed. It is an 

 Indo-Malayan tropical form, argiades being essentially 

 palsearctic. I have seen specimens both of argiades and 

 parrhasius (as I accept it) iinder the names of p)arrhasius 

 and dipora. I have not seen the type specimens of these 

 forms. At present I am merely dealing with argiades 

 (and corctas) and with parrhasius only as bearing on 

 argicules. 



Parrhasius, vaguely defined as ranging from India to 

 Australia, and in its Indian races sunk under argiades by 

 many authorities, has appendages, that, when we note the 

 great similarity of those of a rgiades, corctas, amyntula, and 

 minimus, may be called exceedingly different. 



The distinction in wing-markings that is most constant 

 between argiades and parrhasiiis is that the spots beneath 

 are black in argiades, but nearly of the ground colour in 

 parrhasius, being marked off by the paler circles round 

 them. 



Argiades appears to occur in only the northern and 

 mountainous districts in India. The differences between 

 the appendages of argiades and corctas, though slight, affect 

 several distinct parts of the structure. The clasps in eoretas 

 are wider and heavier basally, the outer angle of the base 

 being full and receding somewhat and more firmly attached 

 to the basal ring. In argiades this attachment is less and 

 the angle looks much more rounded off, than in eoretas. 

 The long spine of the clasp is in corctas long, slender, and 

 straight, as compared with the shorter, thicker, and more 

 curved form in argiades. The spiculation of its extremity 

 affects a rather greater length than in argiades. This form 

 of the spine makes what we may call the shoulder more 

 sloping in corctas, more square and angular in argiades. 

 The soft hair-clothed division of the clasp is more slender 

 in argicules and carries only one or two hairs at most, lower 

 than a point approximately level with the division of the 

 clasp into the two branches, below this where the two 

 clasps oppose each other is a considerable glabrous surface ;
